10 photons each of energy 1.5 eV are made incident on a photosensitive plate whose work function is 3 eV. The number of electrons emitted from the plate will be

Zero

100

Text Solution

Verified by Experts

The correct Answer is:

Zero. Photoelectrons will not be emitted, as the energy of each photon is less than the work function (3 eV).
